[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides an animal semen freezing device with high sperm activity, comprising a liquid nitrogen box 1, a heat preservation cover 2 is installed on the top of the liquid nitrogen box 1, a round rod 3 is installed inside the bottom of the liquid nitrogen box 1, a first turbine 4 and a second turbine 5 are respectively sleeved on the outer ends of the round rod 3, a first gear 6 is meshed on the outer part of the first turbine 4, a second gear 7 is meshed on the outer part of the second turbine 5, a cylinder 8 is sleeved inside the second gear 7, a threaded rod 9 is sleeved inside the cylinder 8, a support plate 10 is installed on the top of the threaded rod 9, a connecting rod 11 is arranged inside the liquid nitrogen box 1, a rectangular plate 12 is arranged inside the liquid nitrogen box 1, a cylinder 13 is installed at the bottom of the rectangular plate 12, a spring 14 is sleeved on the outer part of the cylinder 13, and a ring 15 is installed at the bottom of the spring 14.

[0022] The above scheme is adopted: by opening the heat preservation cover 2, rotating the handle installed on the outside of the round rod 3, and driving the round rod 3 to rotate by rotating the handle, and at the same time, the round rod 3 drives the first turbine 4 and the second turbine 5 installed on the outside to rotate, and the first turbine 4 and the second turbine 5 drive the first gear 6 and the second gear 7 engaged with the outside to rotate, and the first gear 6 and the second gear 7 drive the cylinder 8 to rotate. Since the cylinder 8 performs a threaded motion with the threaded rod 9 when rotating, and the support plate 10 is fixedly connected to the top of the threaded rod 9, the threaded rod 9 can move upward from the inside of the heat preservation cover 2 when the cylinder 8 and the threaded rod 9 are threadedly moved, and at the same time, the threaded rod 9 pushes the support plate 10 to drive the protrusion installed on the outside of the support plate 10 to move along the liquid The rectangular groove opened on the inner wall of the nitrogen box 1 moves vertically upward. When the support plate 10 moves to the rectangular plate 12, it contacts the rectangular plate 12 through the outside of the support plate 10, so that the rectangular plate 12 is forced to squeeze the spring 14 backward. At the same time, the spring 14 is compressed and drives the cylinder 13 to move along the inner wall of the ring 15 into the rectangular groove. When the support plate 10 moves up and does not contact the rectangular plate 12, the spring 14 is reset, driving the cylinder 13 to push the rectangular plate 12 to expand outward, and the support plate 10 is supported by the rectangular plate 12. At this time, it is convenient for the staff to take the animal semen sample placed on the top of the support plate 10. In this process, the risk of frostbite on the skin of the staff when taking the animal semen sample is reduced.

[0023] like Figure 1 and Figure 5As shown, a rectangular groove is provided on the inner wall of the liquid nitrogen box 1, and a circular ring 15 is installed in the rectangular groove; the outer portion of the circular ring 15 is semicircular, and a handle is installed on the top surface of the insulation cover 2; and a spring 14 is installed between the circular ring 15 and the rectangular plate 12.

[0024] The above scheme is adopted: when the support plate 10 moves up and contacts the rectangular plate 12, since the outer part of the rectangular plate 12 is in a semicircular arc shape, when the support plate 10 contacts the rectangular plate 12, the rectangular plate 12 is forced to move backward, and at the same time, the rectangular plate 12 squeezes the spring 14 to be compressed, driving the cylinder 13 to move backward along the inner wall of the ring 15 into the rectangular groove. When the support plate 10 moves up and does not contact the rectangular plate 12, the spring 14 is reset, driving the cylinder 13 to push the rectangular plate 12 to expand outward, and the support plate 10 is supported by the rectangular plate 12, so as to facilitate the staff to take the animal semen sample. At the same time, the rectangular plate 12 increases the stability of the support plate 10.

[0025] like Figures 1 to 3 As shown, a turning handle is installed on the outside of the round rod 3, and the round rod 3 contacts both sides of the inner wall of the liquid nitrogen box 1; a rectangular groove is opened on the inner wall of the liquid nitrogen box 1, and a protrusion is installed on the outside of the support plate 10; the protrusion slides vertically in the rectangular groove.

[0026] The above scheme is adopted: the round rod 3, the first turbine 4 and the second turbine 5 are driven to rotate by rotating the handle outside the round rod 3, and at the same time, the first turbine 4 and the second turbine 5 drive the first gear 6 and the second gear 7 meshing outside to rotate, so that the threaded rod 9 moves up along the inside of the cylinder 8 to push the support plate 10, and the support plate 10 drives the externally installed protrusion to move vertically upward along the rectangular groove, so as to facilitate the staff to take the animal semen sample placed on the top of the support plate 10, and prevent the occurrence of frostbite on the skin of the staff inside the liquid nitrogen box 1.

[0027] The working principle and use process of this utility model:

[0028] First, the staff will place the prepared animal semen sample in the liquid nitrogen box 1 and preserve it. When the animal semen sample is needed, the staff will pull the handle installed on the top of the insulation cover 2 and open it. At this time, the turning handle installed on the outside of the round rod 3 is rotated to drive the round rod 3 to rotate. At the same time, the round rod 3 drives the first turbine 4 and the second turbine 5 mounted on the outside to rotate. The first turbine 4 and the second turbine 5 drive the first gear 6 and the second gear 7 engaged on the outside to rotate, and the first gear 6 and the second gear 7 drive the cylinder 8 to rotate. Since the cylinder 8 performs a threaded motion with the threaded rod 9 when rotating, and the support plate 10 is fixedly connected to the top of the threaded rod 9, the threaded rod 9 can move upward from the inside of the insulation cover 2 when the cylinder 8 and the threaded rod 9 are threadedly moved, and the threaded rod 9 pushes the support plate 10 drives the protrusion installed on the outside of the support plate 10 to move vertically upward along the rectangular groove opened on the inner wall of the liquid nitrogen box 1. When the support plate 10 moves to the rectangular plate 12, it contacts the rectangular plate 12 through the outside of the support plate 10, so that the rectangular plate 12 is forced to squeeze the spring 14 backward. At the same time, the spring 14 is compressed and drives the cylinder 13 to move along the inner wall of the ring 15 into the rectangular groove. When the support plate 10 moves up and does not contact the rectangular plate 12, the spring 14 is reset at this time, driving the cylinder 13 to push the rectangular plate 12 to expand outward, and the support plate 10 is supported by the rectangular plate 12. At this time, it is convenient for the staff to take the animal semen sample placed on the top of the support plate 10. In this process, the risk of frostbite skin when the staff takes the animal semen sample is reduced, and the convenience of the staff to take the animal semen sample is improved.
